Systems and methods for advertising continuity

ABSTRACT

Methods and systems are described for generating content identification files, such as manifest files, for ensuring content and advertising continuity when changes occur during playback. A user device can request content at a particular bitrate, and a first manifest file comprising references to the content and selected associated content such as advertisements can be created in response to the request. While one of the advertisements is being displayed, the user device can request a change, such as for a different bitrate. A computing device, such as a manifest server can access the first manifest file to determine the content and the associated content, such the advertisements, that were intended for the user. The manifest server can then create a second manifest file in response to the request, where second manifest file can be created with the associated content, for example, the advertisements in the first manifest file.

CROSS REFERENCE TO RELATED APPLICATION

This application is a continuation of U.S. application Ser. No. 15/079,831 filed Mar. 24, 2016, herein incorporated by reference in its entirety.

BACKGROUND

Internet Protocol (IP) video can be delivered at different bitrates. A device receiving an IP video stream can request a change in the bitrate of the video stream. If the IP video stream is currently displaying an advertisement, a different advertisement, corresponding to the newly requested bitrate will interrupt the currently displaying advertisement at the old bitrate, causing a negative impact on the user experience. What is needed is a way to transition between bitrates mid-advertisement while maintaining continuity. These and other shortcomings are addressed by the present disclosure.

SUMMARY

It is to be understood that both the following general description and the following detailed description are exemplary and explanatory only and are not restrictive. Methods and systems are described for ensuring continuity with segments of content. For example, the methods and systems described herein can be used to ensure advertising continuity. In an aspect, a user device can request content at a first bitrate. The content request can comprise an identifier associated with the user device. In response to the content request, an advertisement server can generate an advertisement list and deliver the advertisement list to a manifest server. The advertisement list can comprise one or more advertisements that can be displayed during consumption of the requested content. The manifest server can transmit the advertisement list and the identifier associated with the user device to a central computing device. The manifest server can create a first manifest file comprising instructions for acquiring the requested content at the first bitrate and the advertisements in the advertisement list at the first bitrate. The first manifest file can be transmitted to the user device and the user device can use the first manifest file to acquire and playback sequential video fragments of the requested content and advertisements at the first bitrate. In an aspect, the user of the user device can request the content at a second bitrate that is different from the first bitrate. The manifest server can access the advertisement list either local or from the central computing device and can use the advertisement list to create a second manifest file. The second manifest file can comprise instructions for acquiring the requested content at the second bitrate and the advertisements in the advertisement list at the second bitrate.

Additional advantages will be set forth in part in the description which follows or may be learned by practice. The advantages will be realized and attained by means of the elements and combinations particularly pointed out in the appended claims.

In one aspect of the disclosure, a system can be configured to ensure advertising continuity to a user device. Those skilled in the art will appreciate that the present methods may be used in various types of networks and systems that employ both digital and analog equipment. One skilled in the art will appreciate that provided herein is a functional description and that the respective functions can be performed by software, hardware, or a combination of software and hardware. The present disclosure is directed to systems and methods for providing content comprising advertising to a user device such as a computer, a tablet, a mobile device, a communications terminal, or the like. In an aspect, the user device can comprise an identifier which can be globally unique, such as a media access control (MAC) address. In another aspect, the identifier can comprise a token. The user device can request content. For example, the content request can comprise a request for a manifest file. A manifest file can be a sequential list of video fragments to play to render content and/or advertisements. The manifest file can comprise references to content video fragments and/or references to advertising video fragments. The content request can be for a manifest file for content and/or advertisements at a first bitrate. In an aspect, the content request can comprise the identifier. The identifier can be used to identify the origin of the content request, as the content request is forwarded amongst the devices in the network. In an aspect, a computing device, such as a content server, can receive the content request.

The computing device can forward the content request to an advertisement server. The advertisement server can return an advertisement list to the computing device. The advertisement list can comprise a list of specific advertisements in a specific order. In an aspect, the computing device can forward the content request and the advertisement list to a manifest server. In an aspect, the manifest server can be configured to create a manifest file in response to the content request. In an aspect, the manifest server can be configured to create a content state that can be used to track details/parameters of the content associated with the manifest file such as title, bitrate, etc. For example, the content state can track that a program is being streamed to a device at 480p24. The content state can be any data structure suitable for organizing data, such as a list, database table, etc. The content state represents the state of the content at the user device for which the manifest file was created. In an aspect, the content state can be registered with a central computing device. In an aspect, the content state can be transmitted to a plurality of manifest servers. In an aspect, the content state can be maintained at the central computing device. In a further aspect, the plurality of manifest servers can check the content state at the central computing device in response to receiving a request for a manifest file. In an aspect, the central computing device can be configured to link the identifier of the user device with the advertisement list and the content state. In an aspect, the user device can receive the manifest file. In an aspect, the user device can use the manifest file to retrieve and render the content and advertisements. In an aspect, the user device can request video (content and/or advertisement) fragments from the corresponding locations in the manifest file. In an aspect, the requested content and advertisements can be streamed to the user device. In an aspect, the user device can render the content with advertisements interspersed therein. In an aspect, the systems and methods described herein can ensure that a stream change during playing of an advertisement, such as that caused by an adaptive bitrate quality change, results in continued playing of the same advertisement that the customer was viewing. An adaptive bitrate quality change can comprise, for example, a request for a lower quality bitrate in response to a determination that available bandwidth is decreasing. In another example, an adaptive bitrate quality change can comprise a request for a higher quality bitrate in response to a determination that available bandwidth is increasing. In an aspect, the user device can be playing the content at the first bitrate and be in the middle of one of the advertisements when the user device needs to change bitrates. The user device might need to change bitrates because of a change in quality, for example. The user device might require a better quality or a worse quality. For example, network latency can cause a user device to need a lower quality video (e.g., video at a lower bitrate).

The user device can make another content request for another manifest file for the content at a second bitrate. In an aspect, even though the video fragments referred to in the new manifest file are at the second bitrate, the advertising video segments can be the same content as the advertising video segments in the previous manifest file at the first bitrate. In a further aspect, the advertising video segments can be at the first bitrate, the second bitrate, or another bitrate.

FIG. 1 illustrates various aspects of an exemplary environment in which the present methods and systems can operate. In an aspect, the disclosed systems can comprise a user device 102 in communication with a computing device 104 such as a content server, for example. The user device 102 and the computing device 104 can be in communication via a private and/or public network 105 such as a proprietary line from a service provider and/or the Internet. Other forms of communications can be used such as wired and wireless telecommunication channels, for example.

In an aspect, the user device 102 can be an electronic device such as a computer, a smartphone, a laptop, a tablet, a set top box, a display device, or other device capable of communicating with the computing device 104. In an aspect, the user device 102 can be associated with a user identifier or device identifier 108. As an example, the device identifier 108 can be any identifier, token, character, string, or the like, for differentiating one user or user device (e.g., user device 102) from another user or user device. In a further aspect, the device identifier 108 can identify a user or user device as belonging to a particular class of users or user devices. As a further example, the device identifier 108 can comprise information relating to the user device such as a manufacturer, a model or type of device, a service provider associated with the user device 102, a state of the user device 102, a locator, and/or a label or classifier. Other information can be represented by the device identifier 108.

In an aspect, the device identifier 108 can comprise an address element 110 and a service element 112. In an aspect, the address element 110 can comprise or provide an internet protocol address, a network address, a media access control (MAC) address, an Internet address, or the like. As an example, the address element 110 can be relied upon to establish a communication session between the user device 102 and the computing device 104 or other devices and/or networks. As a further example, the address element 110 can be used as an identifier or locator of the user device 102. In an aspect, the address element 110 can be persistent for a particular network.

In an aspect, the service element 112 can comprise an identification of a service provider associated with the user device 102 and/or with the class of user device 102. The class of the user device 102 can be related to a type of device, capability of device, type of service being provided, and/or a level of service (e.g., business class, service tier, service package, etc.). As an example, the service element 112 can comprise information relating to or provided by a communication service provider (e.g., Internet service provider) that is providing or enabling data flow such as communication services to the user device 102. As a further example, the service element 112 can comprise information relating to a preferred service provider for one or more particular services relating to the user device 102. In an aspect, the address element 110 can be used to identify or retrieve data from the service element 112, or vice versa. As a further example, one or more of the address element 110 and the service element 112 can be stored remotely from the user device 102 and retrieved by one or more devices such as the user device 102 and the computing device 104. Other information can be represented by the service element 112.

In an aspect, the user device 102 can transmit a request for content. In an aspect, the request for content can be transmitted to a computing device 104, such as a content server. In a further aspect, the request for content can be forwarded from the computing device 104 to a manifest server 116. In an aspect, the request for content can be transmitted directly to a manifest server 116 from the user device 102.

In an aspect, the manifest server 116 can create a manifest file in response to the request for content from the user device 102. The manifest file can comprise references to video fragments. In an aspect, video fragments can share a characteristic, such as a bitrate, a resolution, etc. In an aspect, the video fragments can be homogeneous or heterogeneous in size, relative to each other. In an aspect, the video fragments can relate to the requested content. In an aspect, the video fragments can relate to advertisements. In an aspect, the references can be uniform resource locators (URLs).

In an aspect, an advertisement server 106 can be queried. In an aspect, the computing device 104 can query the advertisement server 106. In an aspect, the manifest server 116 can query the advertisement server 106.

In an aspect, the advertisement server 106 can create an advertisement list 118 in response to the query. The advertisement list 118 can be transmitted to the manifest server 116. The advertisement list 118 can be transmitted to the computing device 104. In an aspect, a manifest server 116 can use the advertisement list 118 to include references to video fragments of the advertisements in the advertisement list 118 in a manifest file. The manifest server 116 can create a content state 120 associated with the user device 102. In an aspect, the computing device 104 can create the content state 120 associated with the user device 102. The content state 120 can comprise identification of the content represented in the manifest file. In an aspect, the content state 120 can comprise various parameters (e.g., attributes, properties, preferences, options, etc.) of the content represented in the manifest file. The parameters included in the content state 120 can comprise a bitrate of the content. In an aspect, in response to the inclusion of the advertisement list 118 in the manifest file, the computing device 104 can relate the device identifier 108, the advertisement list 118, and the state 120 in a database 114.

In an aspect, the computing device 104 can be a server for communicating with the user device 102. As an example, the computing device 104 can be configured as (or disposed at) a central location (e.g., a headend, or processing facility), which can receive content (e.g., data, input programming) from multiple sources. The computing device 104 can combine the content from the multiple sources and can distribute the content to user (e.g., subscriber) locations (e.g., the user device 102) via a distribution system.

The manifest server 116 can transmit and/or cause the manifest file to be transmitted (e.g., delivered, provided, etc.) to the user device 102. In another aspect, the manifest server 116 can transmit the manifest file to the computing device 104 and the computing device 104 can transmit the manifest file to the user device 102. The user device 102 can request the video fragments at the locations included in the manifest file to create (e.g., assemble, build, retrieve, etc.) video.

In an aspect, the computing device 104 can manage advertising to be included with in content transmitted to the user device 102. In an aspect, the computing device 104 can comprise a database 114 for linking the device identifier 108 with the advertisement list 118 used to create the manifest file used by the user device 102 and/or the content state 120. As an example, when the manifest server 116 creates a manifest file for the user device 102, the manifest server 116 can transmit a signal to the computing device 104, wherein the signal comprises the device identifier 108 of the user device 102. In response to the signal, the computing device 104 can query the database 114 for device identifier 108. If a content state 120 and advertisement list 118 exists for the device identifier 108, then the content state 120 can be checked to see if the advertisement list 118 should be used for the manifest file being created by the manifest server 116. For example, if the content state 120 indicates that the content currently being requested by the user device 102 is not the same as the content currently being presented by the user device 102, then there is no need to use the same advertisement list 118. In an aspect, if the content represented in the content state 120 is the same as the content in the currently created manifest file, and the parameters are the same, then the same manifest file can be returned to the user device 102. The advertisement list 118 can be used in creating a new manifest file if the content represented in the content state 120 is the same as the content in the currently created manifest file, but the parameters are different. For example, if the user device 102 requested the same content, but at a different bitrate, then the same advertisement list 118 should be used to create the manifest file. If it is determined that the same advertisement list 118 should be used, then the manifest server 116 can use the same advertisement list 118 to create the manifest file. If it is determined that the same advertisement list 118 should not be used, then the manifest server 116 can receive a new advertisement list 118 from the advertisement server 106. In an aspect, a state can comprise the advertisement list 116 and content state 120 and be associated with a device identifier 106.

Upon completion of creation of the new manifest file, the manifest server 116 can transmit and/or cause the newly created manifest file to be transmitted (e.g., delivered, provided, etc.) to the user device 102. In another aspect, the manifest server 116 can transmit the new manifest file to the computing device 104 and the computing device 104 can transmit the new manifest file to the user device 102. The user device 102 can request the video fragments at the locations included in the new manifest file to create (e.g., assemble, build, retrieve, etc.) video. In an aspect, video fragments referred to in the new manifest file can be for the same advertisements as in the previous manifest file, only with a different parameters or attributes (e.g., a different bitrate, a different codec, a different size, combinations thereof, and the like). For example, video fragments referred to in the new manifest file can be for the same advertisements as in the previous manifest file, only at the second bitrate.

FIG. 2A illustrates a block representation of an exemplary set of sequential data fragments 200A. In an aspect, the set of sequential data fragments 200A can be assembled using a manifest file comprising references to the set of sequential data fragments 200A, which can be generated by the manifest server 116, for example. In an aspect, the references can be uniform resource locators (URLs). The set of sequential data fragments 200A can comprise data fragments 202A, 206A, and 208A. In an aspect, the data fragments 202A can represent requested content (e.g., video content). The data fragments 206A can represent a first advertisement (e.g., a video advertisement) and the data fragments 208A can represent a second advertisement (e.g., a video advertisement). In an aspect, each data fragment can comprise video and first parameters (e.g., details) related to the video. The first parameters can be content-related parameters. In a further aspect, the first parameters can comprise a first bitrate of the video. In another aspect, the first parameters can comprise a first codec used for encoding and/or used for decoding the video. In yet another aspect, the first parameters can comprise a first format, such as a first size of a display for which the video is formatted.

Turning now to FIG. 2B, the user device or client may request another version of the content, and also another manifest file. This can occur, for example, if the network connection used by the user device changes, and the user device may seek the content in a lower or higher bitrate to accommodate changing network conditions. If the user device 102 requests the same content with second parameters (for example, the same content, but at a second bitrate), then a new set of sequential data fragments 200B can be received from the source comprising data fragments 202B which comprise the content with the second parameters. The second parameters can be content-related parameters. In an aspect, the new set of sequential data fragments 200B can be assembled using a manifest file from the manifest server 116. The new set of sequential data fragments 200B can comprise data fragments 206B representing the first advertisement and/or data fragments 208B representing the second advertisement. To minimize disruption to a viewing experience, the systems and methods described herein can ensure that an advertisement, such as the first advertisement, that is displayed during the request for another version of the content, is displayed after the request for another version of the content is fulfilled. In an aspect, it can be determined that a version of the first advertisement having the second parameters is available and can be included in the data fragments 206B in order to match the second parameters of the requested content. For example, the first advertisement is also available at a second bitrate. However, in some instances, it might be determined that there is no version of the first advertisement available having the second parameters (e.g., the first advertisement may not be available at the second bitrate). In such a scenario, the first advertisement included in the data fragments 206B can be a version of the first advertisement at the same (e.g., original, first) parameters as in the set of sequential data fragments 200A. For example, the data fragments 206B representing the first advertisement can be at the first bitrate. Alternatively, if it is determined that there is no version of the first advertisement available with the second parameters, then a version of the first advertisement included in the data fragments 206B can comprise third parameters (e.g., not the same parameters as originally delivered version of content nor the same parameters as the newly requested version of content). For example, the first advertisement can be at a third bitrate. The third parameters can be content-related parameters. The third parameters can be a closest available version of the first advertisement to the second parameters. For example, the third bitrate can be a bitrate closest to the second bitrate at which the first advertisement is available. The third parameter can be closer to the second parameter than the first parameters. For example, the third bitrate can be closer to the second bitrate than the first bitrate. Although the examples focused on bitrates, other parameters (e.g., codec used for encoding, format, size, etc.) can be used.

FIG. 3 illustrates an exemplary display in accordance with the systems and methods described herein. In an aspect, display 302 shows content 304 at a first bitrate. In another aspect, the display 302 can represent the content 304 encoded by a first codec. In yet another aspect, the display 302 can comprise a first size and can represent the content 304 formatted for the first size. In an aspect, display 306 can represent the same content 304 but with a second parameter. In a further aspect, the display 306 can show content 304 at a second bitrate. In an aspect, the content 304 at the first bitrate can be at a lower bitrate than the content 304 at the second bitrate. In an aspect, the content 304 at the first bitrate can be at a higher bitrate than the content 304 at the second bitrate. In another aspect, the display 302 can represent the content 304 encoded by a second codec. In yet another aspect, the display 302 can comprise a second size and can represent the content 304 formatted for the second size. In an aspect, the first size can be greater than the second size. In an aspect, the first size can be less than the second size. In an aspect, the display 302 can represent the content 304 displayed when a buffer comprises less than and/or equal to a predetermined threshold number of video frames or other units of the content 304. In an aspect, the display 306 can represent the content 304 displayed when a buffer comprises more than and/or equal to a predetermined threshold number of video frames or other units of the content 304.

FIGS. 4A and 4B illustrate block diagrams representing an exemplary system and architecture. The methods and systems described herein can be used in conjunction with content comprising any number of attribute or parameter options. For example, FIGS. 4A and 4B illustrate content comprising multiple bitrate options. Turning first to FIG. 4A, a user device 102 (e.g., a video player or client) can request content at a first bitrate 404 from a content provider or content delivery network 410. In an aspect, the content can also be available from the content provider 410 at a second bitrate 406 and a third bitrate 408. In response to the request, the content provider 410 can query an advertisement server 106. The advertisement server 106 can determine that Advertisements A1, A2, and A3 should be inserted into the requested content and returned to the user device 102. A first manifest server (M1) 116 of a plurality of manifest servers (M1 . . . Mn) 116 associated with the content provider or deliver network 410 can create and deliver a first manifest file to the user device 102. The first manifest file may comprise references to the requested content at the requested bitrate 404 and references to Advertisements A1, A2, and A3 at the requested bitrate 404. In an aspect, the first manifest server 116 can create state information 402 associated with the first manifest file, where the state information 402 can comprise all of the parameters and attributes of the content for which the manifest file was created. The manifest server 116 may transmit the state information 402 to one or more of the rest of the plurality of manifest servers 116. In another aspect, the first manifest server 116 can create the state information 402 and transmit the state information 402 to a central location accessible to the plurality of manifest servers 116. In an aspect, the state information 402 can comprise the advertisement list and content state 120 and be associated with a device identifier 106. The state information 402 can be associated with a particular manifest file that was generated and/or sent to a user device. The state information 402 can be stored as a separate file from the particular manifest file, linked by an identifier(s) or the state information 402 can be stored as part of the particular manifest file. The result is that the particular manifest file can be used to readily provide a location for a version (e.g., content/advertisement at a specific (or proximate) requested parameters) of requested content/advertisements that best fits a request by referencing the state information 402.

Turning now to FIG. 4B, the user device 102 can request the content at the second bitrate 406 from the content provider 410. The request can be sent or received after a portion of the content has already been transmitted to the user device 102, or consumed by a user of the device 102. In an aspect, any of the plurality of manifest servers 116 associated with the content provider or delivery service 410 can receive the request and check the state information 402. In an aspect, the manifest server 116 in receipt of the request or a centrally located computing device 104 can recognize that the requested content at the second bitrate 406 is the same content currently being consumed by, or delivered to the user device 102 at the first bitrate 404 (e.g., via a content identifier). For example, the manifest server 116 in receipt of the request (or a centrally located computing device 104) can recognize that the content currently being consumed by, or delivered to, the user device 102 comprises the same content identifier as the content currently being requested and that the content is currently being consumed or delivered with parameters different from the parameters currently being requested. In another example, the manifest server 116 in receipt of the request or a centrally located computing device 104 can access state information 402 to match the content identifier of the content currently being consumed by, or delivered to the user device 102 with the content identifier of the content currently being requested and access the state information 402 to determine that the content is currently being consumer or delivered with parameters different from the parameters currently being requested.
